Image-manipulation software is being used to create counterfeit scanned documents to aid cybercriminals in fraud efforts.

Some companies that use scanned documents for identity verification have specialized systems and tools that can detect image modifications, Kamarov said. When there is suspicion about the authenticity of a scan, the anti-fraud teams will request images with better quality to verify that they are really created by the user, he said.

However, sometimes companies don't have the resources to perform detailed checks of incoming scans and criminals are exploiting this, Komarov said.
